WALTER WRIGHT, OF NEW YORK, N. Y., ASSIGNOR TO UNDERWOOD COMPUTINGMACHINE COMPANY, OF NEW YORK, N. Y. A CORPORATION OF NEW YORK.

COMBINED TYPE-WRITING- AND COMPUTING MACHINE.

Application filed December 1, 1911.

To all whom it may concern:

Be it known that I, lVAL'rnu WRIGHT, a citizen of the United States,residing in New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in CombinedType-Writing and Computing Machines, of which the following is aspecification.

This invention relates to a pick-up mechanism for traversing thetraveling element of a computing head or totalizer in a combinedtypewriting and computing machine of the Underwood-Wright type, and isan improvement on the application of Wright and Degener, No. 543,603,filed February 12, 1910.

In a combined typewriting and comput ing machine, the columns of numbersto be written and computed are generally spaced apart, and ofteninterspersed or separated by descriptive matter, so that th aggregatelength of the actual number of letter spaces used for numbers to becomputed is considerably less than the length of the typewritten line,and thus of the carriage. Even in the case where a computing head isusedto add vertically each individual column of numbers, it isunnecessary to have a computing head or totalizer of equal length tothat of the typewritten line or that of the carriage. Inasmuch as thtraveling element of the computing head should travel concomitantly withthe carriage of the typewriter when computing and remain stationary whennot computing, I have made provision, when a shorter totalizer orcomputing head than the carriage is used, for a pickup mechanism whichwill cause a movement of the traveling element corresponding to that ofthe carriage when the machine is writing and computing numbers, andwhich will allow the carriage to travel freely when not computing, whilethe traveling element remains behind.

By this arrangement, it is possible to obtain a greater equivalentcapacity by using a single long totalizer of a given number of wheelsthan would be available from the use of a number of small totalizers,the aggregate sum of whose wheels equal the num ber of wheels in thesingle long totalizer. With a single totalizer, any variety of computingcolumns can be used, either limited to one digit, or two digits, or anynumber of digits 11p to the capacity of thelong Specification of LettersPatent.

totalizer. With a number of small totalizers, each must be capable ofcomputing the maximum sum desired, which is generally 999,999.99. Itwill be seen then that if a column whose greatest number is not over 99is needed to be computed, many computing wheels will necessarily beidle. In the present invention with a singl long totalizer, only one ortwo computing wheels need be idle for each computing zone or column.

A featur of this invention is to provide a mechanism which willautomatically pick up the traveling element of a computing head ortotalizer at predetermined points in the travel of the typewritercarriage, and drop said traveling element at other predetermined pointscorresponding respectively to the beginning and end of columns ofcomputation.

Another feature of this invention is to lock th traveling element of thecomputing head in any stationary position against accidental movementwhen not being traversed, and also to automatically release thetraveling element of the computing head at the actuation of the pick upmechanism, to tr verse the traveling element.

A further feature of this invention is to enable the rendering of apick-up mechanism ineffective to traverse the traveling ele ment of acomputing head when it is desired to typewrite without computing.

The invention is illustrated in connection with an Underwoodl Vrightcombined typewriting and computing machine in which a master wheel isgiven a rotation, when a numeral key is struck, of an extentcorresponding to the particular numeral key. A relative movement isprovided between the master wheel and a series of computing wheelsarranged side by side, so that the master wheel will cooperatesuccessively with each computing wheel in the series as the numeral keysare successively struck, whereby the computation will be registered upon the dial wheels operated by the com puting wheels.

In this case, the master wheel is shown to ,be stationary, and thecomputing head casing carrying the series of computing and dial wheelsis shown to be traveling, in order to obtain the relative movement between the master wheel and the c mputing Wheels,

The carriage of the typewriting mecha nism is provided with 'a rackmovably mounted thereolnsoas to-swing into and out of cooperation with apick-up dog carried by some part of thetraitelingelement of thecomputing head or totalizer, which in this instance is shown to be thecasing containing the computing and dial wheels.

The rack is also provided with slots located at letter space intervalsfrom each other, so as to carry, at any point corresponding to a letterspace on the work sheet on the carriage, actuators in the form ofadjustable, interchangeable and reversible lugs, which, when placed inonev position, will actuate a shifter in one direction, and when placedin another position, will actuate the shifter in the opposite direction,so that the frame carrying the raekwill swing to move the rack out ofand into engagement with the dog on the computing head, enabling saidcomputing head to respectively remain stationary and travel with thecarriage.

The swinging frame, concomitantly with the connecting and disconnectingmovement of the rack, enables the tilting of a locking pawl torespectively disengage and engage a locking rack carried by thetraveling element of a computing head, thereby respectively permittingand preventing the movement of said traveling element.

A throw-out is provided in the form of a cam lever, which shifts theswinging frame, and thus the rack carried thereby, to a position wherethe latter cannot engage the pick-up dog. The throw-out is automaticallylocked by a spring in either position of adjustment. 7

Other features and advantages will hereinafter appear.

qlieferring more particularly to the sepa rate parts of this inventionas embodied in the form shown in-the drawings, 1 indicates letter keysand 2 numeral keys, which are mounted ,on key levers and. actuate,through theintermediary of hell cranks 4, type bars 5, so as to swingthe latter up rearwardly against the front side of a platen 6 mounted torotate, on a carriage 7, which travels on ways 8 under the control of anescapement mechanism 9, which is released, at the actuation of eachcharacter key, to feed the carriage step-by-step in a manner common toan Jnderwood typewriter.

As described in the prior application of "W right and Degener No.543,603, filed Feb. 12, 1910, each of; the numeralkeys 2 is adapted topull on a link 10, so as to rock a bell crank 11, thereby drawing on alever 1 through the intermediary of a link 13, so as to rock said lever12 about its pivot 14:, whereby a jack 15 carried by said lever willproject one of a series of pins 16 mounted on an index or valuatingwheel 17. These pins 16 are arranged to normally stand opposite to aseries, of jacks 15, of which there is one for each of the numeral keysfrom 1 to 9. The pins 16 are located at variable distances from anescapement wheel 18, which is locked, by the engagement of a secondescapement wheel 10, with locking projections 20 on a shaft 21.

The shaft 21 is rocked at each actuation of a numeral-key, so asto'permit the rotation of the escapement wheels 18 and 19, and thus ofthe valuating or index wheel 17, until the next projected pin comes inengagement with the escapement wheel 18. The rocking of the shaft 21 maybe accomplished by the bell crank 12 engaging a collar 120 and pressing:the same to one side against the tension of a spring 121, so as to rocka lever 122 connected to this collar and also connected to an arm 123 onthe rock shaft 21 through the intermediary of a link 125. The spring-121will return the collar and the rock shaft 21 after the pressure on thenumeral key: has been removed.

The above mechanism may be te mod the index escapement or valuatingmechanism, inasmuch as it controls the extent of rotation of a. masterwheel 22 provided in a computing head or totalizer 23; The connectionbetween the-valuating wheel 17 and the master wheel 22 maybe of anysuitable character. such as that shown and described in aforesaidapplication No. 3,603, and it is not. considerednecessary toillustratecand describe the same in this case. The connection is such,however, that as each of the numeral keys is actuated, it will cause arotation of the master wheel 22 in the computing head 23 an amountcorresponding to the particular value of the numeral key. The masterwheel in this instance is shown to be stationary and to operate aeriatimeach one of a series of computing wheels 24 provided in the computinghead 23, the casing 25, which contains the computing wheels 24, be ingmoved step-by-step so as to bring the master wheel 22 successively inengagement with each of the computing wheels 24.

The computing wheels 24 are provided with inwardly projecting teeth,which form internal gears meshing with the master wheel 22. Thesecomputing wheels 24 are likewise provided with external teeth, whichform external gears 26, which mesh with corresponding gears 27 carryingdial wheels 28 adapted to exhibit the numerals run up by the numeralkeys through an opening 29 in the casing 25. A complete rotation of eachcomputing wheel 24 is carried to the next higher computing wheel bymeans of tens carrying mechanism, indicated generally at 30, which maybe of any suitable character, such as that shown and described inaforesaid application No. 543,603.

As shown in the drawings, the computing head is of a type adapted tosuccessively compute individual vertical columns, and might beconsidered to embody a series of individual vertical column computingheads arranged side by side. Inasmuch as the computed columns occupygenerally, in the aggregate, less actual space than the space 1 of thetypewritten line, the computing head need not be as long as thetypewritten line, and. thus not as long as the carriage itself. Inasmuchas the carriage, however, travels its full length, it is unnecessary topermit the travel of the computing head 23 except at such times as it isdesired to compute. To on able this intermittent traveling of thetraveling element of the computing head, which in this instance is shownto be the casing carrying the computing and dial wheels, there. isprovided a pick-up mechanism, which embodies a rack 31 carried by thecarriage and a dog 32 capable of engaging with teeth 33 located atletter space intervals on the rack 31.

The dog is mounted onthe traveling elen'ient of the computing head,which in this instance is the casing The casing may be supported in anysuitable manner as by means of rollers 34, which run on tracks orrails-35. The rack 31 is movably mounted on the carriage 7 so that itcan be swung into and out of engagement with the dog 32. The method ofmounting the rack may be of any suitable character, and. in thisinstance is shown to be accomplished by a frame 36, which is pivotallymounted on the carriage frame 7 and embodies a plurality of hangers 3'7pivotally mounted at 38 on the carriage and connected together by a rail39. The weight of the fame 36 and the rack 31 car ried thereby, issuflicient to normally force the teeth 33 of the rack 31 in engagementwith the dog In order to force the teeth 33 out of engagement with thedog 32, there is provided a shifter 40, which is shown in the form of alever pivoted at 41 and having an ofi-set finger 42, which can engagethe rail 39 at any position of the carriage 7. To actuate the shifter40, it is provided with a following roller 43, which, during themovement of the carriage, will be actuated toward the carriage by theshort side 45 of an actuator 46, shown in'the form of a lug detachably,reversibly and adjust-ably connected to the rack bar 31 by engaging inpairs of slots 47 and 43 arranged at letter space intervals.

The positionof a lug arranged to engage the follower 43, so as to forcethe rack 31 out of. engagement with the dog 32, is shown at 49 in Fig.lVhen the shifter 40 has been once actuated by a lug 46 in this manner,it is held in its disconnecting position by a detent 50, which includesa member 51 on the shifter lever 40 and a spring latch or detent 52, onthe fixed portion of the frame, engaging with said member. It will. benoted that the rail 39 is provided on. its inner side throughout itslength with an inclined or cam surface 53 which the finger 42 of theshifter 40 will engage when it is forced outwardly to disconnect therack 31 from the dog 32. It will be seen that this action will be in thenature of a cam action forcing the rail 39 upwardly until the end of thefinger 42 rests in a groove 54 provided on the under side of the rail.This groove is so formed that when the finger 42 has once entered thesame, it will support the rail 39, and thus the rack 31, in itsdisconnected position.

In order to return the shifter from the full line position shown invFig. 5 to the dotted line position so as to permit the rack 31-to fallin engagement with the dog 32, the lug actuators 46 may be reversed tothe position shown at 55 in Fig, 5, corresponding also to that shown inFig. 6, where it will be seen that an extension leg 56 pro-- vided onthe lug is located in spaced relation from the rack 31, so as to permitthe following roller '43 to pass between this extension leg and the rackand be forced toward the rack by a cam edge 57 provided on this leg.

' For the purpose of rendering the pick-up mechanism between thecarriage and the computing device ineffective, there proyided athrow-out indicated at 58,'which is shown in the form of a cam leverpivoted at 59 and having a cam surface 60 adapted to engage under one ofthe hangers 37, to raise the whole frame 36, and the parts carriedthereby, to such a position that the teeth 33 on the rack 31 will beunable to drop into engagement with the dog 32. It will be noted thatthe cam lever can be detained in either position of adj ustinent by aspring 61, which is secured at one end to a portion of the carriageframe, and at its other end to the cam lever, in such a position that itwill swing to either side of the pivot 59 of the cam lever, when thelatter is swung to its two positions of adjustment. This detainingaction is aided by the fact that a portion of the cam lever, indicatedat 62, will rest on the frame of the carriage in one position, and anangular portion 63 of the lever will Test against the side of the hanger37 in the other position. This action is clearly shown in Fig. 2.

lVhen the throw-out is in use to render the pick-up mechanismineffective, and also when the throw-out is not in use, and the pick-upmechanism is disconnected through the actuation of the shifter 40, it isdesirable to lock the traveling element of the computing head againstaccidental movement. For so this purpose, there is secured to thetraveling element a locking rack 64, which is engaged by a locking pawl65 normally thrust to its engaging position by a spring 66. This lockingpawl 65, however, is provided with a contact roll 67, whereby, when theframe 36 falls to effect a connection of the rack 31 with the dog 32,the rail 39 will engage with this contact roll 67 and force the toe ofthe pawl 65 out of locking en- 49 gagement with the locking rack 64, soas to permit the movement of the traveling element of the computinghead.

While the connection of the rack 31 with the dog 32 might be dependedupon to return the traveling element of the computing head during thereturn motion of the carriage, it may be desirable to make the returnsure, and for this purpose the traveling element of the computing headis provided with 29 an extension or lug 68, which projects upwardly to aposition where it can readily be engaged by an enlargement 69 on one ofthe lugs or actuators 46 located at such a position that it willcompletely return the b5 traveling element when the carriageiscompletely returned. The relative position of the master wheel to thedial and computing wheels of the computing head may be indicated by apointer secured to a fixed portion of the frame and located injuxtaposition to the opening in the casing through which the dial wheelsare viewed. V. 5 To eliminate the intermittentconnection between theawning- 61mm or the computing head and the carriage, and cause apositive continuous connection, any one of the actuators or lugs 46 canbe reversed, that is to say, turned bottom side uppermost, so that atongue 71 thereon will en- 7 gage with a tooth 72 on the dog 32.

The operation of the device will be readily understood when taken inconnection with the above description. lVe will assume that theoperation starts with the pick-up mecha- 75 nism disconnected so thatthe carriage is free to travel without carrying the traveling element ofthe computing head. In this relation, any suitable matter can be writtenon the work sheet without moving the traveling o element of thecomputing head. When the computation starts, that is to say, when thenumeral keys are actuated to begin a computation, the first actuator orlug 46, arranged in the position indicated at 55 in Fig. 5, will comeinto contact with the following roller 43, so that the cam surface 57 onthe extension lug 56 thereof will force said following roller toward therack 31, thereby removing the finger 42 from engagement with the groove54in the rail 39, so that said rail 39, together with the frame 36, ofwhich it forms a part, and the rack 31 carried thereby, will bepermitted to fall clownwardly and inwardly until the teeth 33 en gagethe tooth of the dog 32 on the traveling element of the computing head.

When the frame 36 and the rail 39 fall down to this position, the underside of the rail 39 will engage the contact roller 67, so as to removethe toe of the locking pawl 65 from engagement with the teeth of thelooking rack 64, thereby permitting the travel of the traveling elementof the computing head. At the end of a number to be computed, or at theend of a certain column written on the work sheet on the carriage,another actuator or lug 46 will be arranged in one of the letter spaceslots on the rack 31 in a position indicated at 49, Where the short endthereof having the rounded edge 45 will be in a position to engage thefollowing roller 43, so as to force it from the dotted line positionindicated in Fig. 5 to the full line position, whereby the-finger 42 on115 the shifter 40 will engage the cam surface '53 and gradually forcethe rail 39 outwardly and upwardly until the teeth 33 on the rack 31.areforced out of engagement with the dog 32. When this occurs, the end ofthe 1 finger 42 will have entered the groove or channel 54 so that itwill support the frame 36 and the rack 31 carried thereby in thedisconnected position of the rack. The shifter 40 will be held initsshifted position 125 by means of the detent 50. The instant the rack 31rises, so as to disengage the teeth 33 from the dog 32, the spring 66will act to force the toe of the locking pawl 65 into engagement withthe locking rack 64 by v1r-. 0

tue of the fact that the rail 39 has been removed from its depressingcontact with the contact roller 67.

If it be desired to compute in a second column, a second pick-up lug l6is inserted on the rack 31 at such a position that the numbers in thesecond column will not be inserted in the totalizer until the totalizerhas been picked up by the typewriter carriage and carried idly alongseveral letter spaces in said second column. This will prevent thenumbers in the second column from overlapping, by arrying over, orotherwise, into the first column. The number of letterspaces in thisidle travel usually need not be great, and never need be more than thenumber of digits in the total to be obtained. In other words, theoperative in using this machine is not confronted with the necessity ofhaving a large stock of expensive totalizcrs of assorted sizes and ofbeing obliged to select a totalizer having the proper number of wheelsfor each new job of tabulation, but has only to adjust the lugs 1-6 onthe racks at such intervals as to cause the typewriter carriage toselect groups of wheels of the desired lengths in the single longtotalizer 23.

To disconnect the totalizer from the typewriter carria e after thenumbers have been written and computed in the second column, a seconddisconnect lug 46 is inserted in the rack 31. Similar lugs 46 may beplaced in the rack 31 for any desired number of columns within thecapacity of the mechanism.

The return motion of the traveling element may be obtained by theenlargement 69 on one of the-actuators e6 engaging the extension 68 onthe return motion of the car riage.

If it is desired to connect the traveling element of the computing headcontinuously with the traveling carriage, without the intermittentconnection and disconnection, one of the actuators or lugs l6 may bereversed, so as to permit the tongue 71 thereon to engage with the tooth72 of the dog to drive the tetalizer forward, while the enlargement 69will return the totalizer.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
